Mutants show loss of ventral denticles and all remaining denticles point posteriorly.
Homozygous clones result in minor effects on wing vein patterning, but do not result in significant outgrowths.
Eggs produced by females carrying homozygous follicle cell clones are almost wild type, with only a very mild expansion of the operculum, while dorsal appendages and the micropyle are normal.
